No actual clue since I've never even heard of that comic before, but it's possible that the story's similar to that of many other sprite comics.

It's not uncommon for sprite comics to be deleted by their authors. The most likely scenario is that they simply lost interest in the project, and didn't feel that the comic was a good representation of their skill, and chose to take it down. Some authors even feel outright shame about their old sprite comics or their past involvement in fandoms, especially if there was drama involved. Said drama can also drive an author to quit and delete their comic, just to avoid it and forget it.

Same thing happened with Kabutroid who wrote Planet Zebeth. It's not on this site, but basically the same thing happened where the whole thing disappeared, the author, the comic, gone. Which is way sad because his page count was in the thousands. :/ Really saddens me when something like a whole comic just disappears and then I think to myself, I might be the only person to know this existed one day... I think I remember taking a glance and MBN7, I really enjoy the game series. That's too bad, I feel for all his fans.

EDIT: Actually I just checked, it looks like Zebeth has returned to me. :') It was gone for months though.
